I Haven't Been Able To Find Any Manhwa Or Other Work That Portrays This Particular Toxic Relationship Dynamic Properly. If You Understand What I'm Looking For, Please Recommend Something!

A toxic romance manhwa where the ML is obsessively devoted to the FL but will never let her go, which is precisely why she cannot love him. She either loves another man or despises the ML, knowing that she can never truly escape him. Despite their unequal circumstances, both hold a degree of power over the other.

The ML is a powerful, dangerous man who can have virtually anything he desires, except the love of the woman he is obsessed with. She is his sole weakness, and his devotion to her is so consuming that he refuses to let her go, essentially forcing her into a relationship against her will, despite knowing how much she hates him.

In return, the FL is cold, stoic and often cruel towards him. She makes no effort to hide her contempt, speaks to him harshly and deliberately uses his obsessive love and devotion to her advantage. Their relationship is defined by a twisted power dynamic in which he has the power to keep her, but she has the power to hurt him in ways no one else can.

Note: To add further context, this was heavily based on the relationship between the Marchioness and her late husband in A Swan's Grave, as well as I Failed to Oust the Villain.
